A manga adaptation of the "Mononoke: Karakasa" movie. The setting is the Ooku, a "women's garden" where men aren't allowed, as well as a bureaucratic institute. Two new maids, Asa and Kame, step into the Ooku; Asa is a smart, beautiful woman looking to advance her career, while Kame is looking for her place in the Ooku. From the very first day, these polar opposites are forced into a weird "ritual" to integrate them into the group. Little by little, "something" seems to cover them. And then, a sudden tragedy occurs.
